We assessed the age-related changes of SWI and phase image at the subependymal nodules in infants and children with tuberous sclerosis. There was no signal loss on SWI and no phase shift on phase image at the subependymal nodules in neonates, those changed by aging. The occurrence of the phase shift at the subependymal nodules was identified around 1-year-old, while signal loss on SWI appeared after 2-year-old. The manifestation of the phase shift at the subependymal nodules seems to precede that of signal loss on SWI.
